UNITED STATES PATENT OFFICE CUSHION SUPPORT v Hugh C. Lord, Erie, Pa. Application February 12, 193s, serial No. 190,277 9 claims. (c1. 287-85) The present invention is designed to provide is secured by a nut I4 which is provided with a a cushion support and, as exemplied, is applied lock washer I5. Y to a chair leg. Chairs or seats in automobiles, 'I'he inner member extends below the bottom airplanes and other vehicles are not only subof the outer member of the support and thus 5 jected to the weight of the person using the spaces the support from the oor. The leg 2 chair but are subjected to very severe strains by preferably extends downwardly to the bottom reason of the user exerting tilting pressure on of the outer member and is therefore spaced the seat, thus tending to pull part of the legs of from the floor. The bolt extending through the the chair upwardly and very materially increase slot I3 prevents the loosening of the bolt and l the pressure on the other legs. In airplane conthus assures a secure connection between the struction there is a further requirement and that leg and the floor. The length of the slot issuch is in the very definite securing of the chair so as to give the normal freedom of movement to that the chair in shocks or accidents will Vnot the support but to finally and positively limit break loose and increase the hazard in this way. this movement should there be an abnormal l The use of the support is designed to accomstrain on the chair parts. Thus should there plish the purpose of anchoring the cushioning be a complete failure of the rubber the chair and also anchoring the attached chair or other connection would be maintained. It will be noted article in a very simple, rugged and secure manthat the relation of the parts, including the lost'l ner.

6. In combination a hollow chair leg; a support for the leg; a mounting between the support and the leg comprising an outer element attached to the leg, an inner element attached to the support, and an intervening cushion of rubber; and a lost'motion connection with theleg and inner element, the lost motion connection being housed in the space above the rubber cushion providing free movement between the leg .and the support and preventing separation thereof.

In combination of chair leg; a support for the leg; a mounting between the support and the leg comprising an outer member, an 'inner member, and a rubber cushion between the members, one of the members being attached to the leg and the other to the'support; and a lost motion safety conne-.tion supplementing the connection formed by the members,` the members providing free relative movement between the members in noncontact relation in normal operation 'and limiting the separation of said members.

8. In a joint, the combination of outer and inner members; a rubber bushing between the members, one of the members having perforations extending therethrough Aand the other member having spaced abutments; and a crossmember extending through 'the perforations and between the abutments, said members being out of contact relation in the joint under normal operating conditions.

9. In a joint, the combination with members to be connected; of a joint between the members, said joint comprising an outer element, an inner element, and a rubber cushion between the elements; 4means attaching the joint to the members; and a lost motion connection between the members providing free relative movement between the members, in non-contact relation under normal operating conditions, but limiting the motion at'both extremes of the motion and housed in a space offset in the direction of motion from the rubber.
